Senate passes bipartisan ocean monitoring and research act

Ocean Core Sampling

On January 8, the Senate unanimously passed Senator Roger Wicker’s (R-MS) Coordinated Ocean Monitoring and Research Act (S.1425). The bipartisan bill revises and reauthorizes the Integrated Coastal and Ocean Observation System (ICOOS) Act of 2009, which established the Integrated Ocean Observing System (IOOS) to consolidate and coordinate the efforts of hundreds of federal, state, and local observing programs through fiscal year (FY) 2021. In addition to reauthorizing the ICOOS Act, S.1425 promotes best practices regarding data sharing for public use, investment in autonomous unmanned underwater and surface ocean research vehicles, closing gaps in high frequency radar, and assisting Coast Guard search and rescue operations.

EARTH: Seeing the Seafloor in High Definition

As the U.S. celebrates National Oceans Month in June, scientists who study the seafloor are excited because they believe that humans will end this century with a far better view of our seafloor than at any other time in human history. Geoscientists have been mapping land on Earth, and even other planets in our solar system, in high definition for years, but the picture of the ocean floor has remained blurry for the most part. But with advances in engineering, what lies beneath is starting to come into much better focus.

EARTH: How to Feed 11 Billion People

The challenge of feeding our planet's growing population is one of critical importance - it will perhaps be the most important challenge of the 21st century. As the human population continues to rise, geoscience is informimg experts, suggesting major shifts in agriculture must be taken to prevent rampant food insecurity by the year 2050.

EARTH Magazine: Are slow-slip earthquakes under Tokyo stressing faults?

New research examining plate movements under Tokyo has found that since the massive magnitude-9 Tohoku earthquake and tsunami in March 2011, recurrence intervals for nondamaging slow-slip quakes beneath Japan’s capital have shortened. That has left seismologists wondering if this aseismic creep could be signaling a countdown to Tokyo’s next “big one.” Read more about scientists’ estimations of Tokyo’s seismic risk in the August issue of EARTH Magazine.

EARTH Magazine: Precise to a fault: How GPS revolutionized seismic research

Prior to the quake, geoscientists had placed GPS markers in and around the San Francisco area. Immediately after the quake, researchers converged on the area to collect and compare the pre- and post-quake GPS data, which revealed the direction and speed of surface movements, allowing scientists to infer the pattern of slip on the fault plane that had ruptured far underground.
